I attempted with the purchased value band, but as far as the middle of the water wells, mud etc are accumulated, I can not penetrate more than that. I think that it is handy for penetration of drain pipe etc. It is planned to use it. It seems necessary to start from the thin wire of about 2-3 millimeters to penetrate the current pipe. Is there a suction device for it?
